Dear Mr Shafie, Not so good news...I would not say, that we make heavy use of namespaces. Just in the MathML and in the DCMI. Your first suggestion (change editor) would put us back to square 1. I can try the automatic conversion, although I have no idea about unwanted side effects (dtd-invalid xml-data). So I have 3 questions (which have little to do with xmlmind):
- What parameters do you recommnd for the "trang dtd input module (http://www.thaiopensource.com/relaxng/trang-manual.html#dtd-input)"? - Will the XML-file still "look like now" (dtd-declaration and to on...) even if it is checked by the schema - Do you recommend XML schema or RELAX NG?
